Don’t miss a single sound. Listen.
Listen Technologies Corporation believes your audience is there to learn or to be
entertained, and that they ought to enjoy a personalized, enriching auditory
experience. Many environments present challenges for the listener to clearly hear,
appreciate, and understand what is being communicated. Listen is committed to
ensuring that our products provide the auditory experience your audience deserves.
Language Interpretation
Listen’s line of portable FM products deliver on this commitment by providing a
carefully tuned system of products that makes the process of specifying, ordering,
and using the system simple and straight forward. A Listen FM system functions like a
low power radio station that broadcasts sound to receivers within range of the
transmitters. The Portable FM system is a great way to deliver interference-free, clear
sound directly to each individual, dramatically enhancing their individual experience
and ensuring that they get the full experience they desired.
Don’t miss a single sound. Listen.
Imagine being in a foreign country to do business, but unable
to understand what your business partners are saying.
A portable FM system delivers high quality sound to every
listener in your group, allowing your interpreter to facilitate
communication in even the loudest of environments.
Press Conferences
Tour Group
Have you ever been on a tour and not been able to hear the
information being provided by the tour guide? When you are
on a tour you are there to not only see what is being shown, but
also to hear what is being said. Unfortunately, sometimes the
environment itself poses hearing difficulties. Listen solve this
problem by ensuring visitors get a clear and interference-free
listening experience.
A press conference can be an atmosphere charged with
excitement and commotion. When news is being reported, you
want to be sure you are hearing the message clearly and without
disruption. Your ability to do that relies on your ability to
understand what you are hearing. A Listen system brings the
information directly to your ears as if the speaker is giving you
the inside scoop on the news.
Employee Training
1
When you are trying to learn, hearing the message is
imperative. A Listen system can deliver an instructors
voice directly to the student’s ears providing them
with the ability to understand and process the
information more effectively. The end result is more
effective training and instructors who are less
fatigued because they don’t have to speak loudly.
